Industrial Refrigeration

• Cold Storage
• Freezing Systems
• Process Cooling

TRJ Refrigeration designs and builds industrial refrigeration systems for cold storage, process cooling, water chilling, individual quick freezing or IQF systems, and have the capability to interface with flash freezing systems such as cryogenic freezing and nitrogen immersion systems. Many systems as shown in the pictures below are incorporated into precooling systems we offer such as forced air cooling, portable and modular ice plants, stand alone industrial ice makers, hydrocoolers, and liquid ice systems.

and Modular Ice Plants

Packaged Refrigeration Systems
Most systems can be pre-packaged as shown above. Some of the advantages of factory packaging are:

  • Reduces field installation time and costs
  • Modular construction allows for future relocation of equipment
  • Up to 500 TR capacity using halocarbon or ammonia
  • Complete with compressors, condensers, all vessels and electrical equipment required
  • Factory construction offers a high degree of quality control over construction, testing and finishing
  • Can be integrated with any modular ice plants, portable ice plants, industrial ice making systems and forced air coolers
TRJ provides customers with a comprehensive range of precooling systems and services such as feasibility studies, system design, build, installation, service and maintenance, existing system analysis and recommendations for performance improvements. TRJ utilizes superior technology and advanced refrigeration techniques to provide innovative solutions to your specific precooling and freezing needs. Designed in accordance with applicable industry standards, our refrigeration systems meet or exceed the requirements or suggestions and recommendations of ASHRAE, IIAR, RETA of which we are members.
